BRUSSELS (Reuters) - Ryanair CEO Michael O'Leary said on Wednesday he will meet with senior Boeing executives later in the day in Dublin to discuss prolonged delays in plane deliveries as a crisis at the U.S. planemaker deepens.

Speaking to Reuters on the sidelines of an aviation conference, he said he will also discuss the certification of Boeing's 737 MAX 10 aircraft and ongoing issues with oversight following the Jan. 5 mid-air loss of a panel on a new Alaska Airlines MAX 9.

The meeting will be with the "highest levels of management" at Boeing, he said, without identifying who.

"We are working closely with Boeing. (...) Boeing are still producing great aircraft, but there's no doubt in our mind that on the shop floor, the systems and the quality control in Seattle need to be improved," he said, referring to Boeing's main manufacturing hub in Washington.

Boeing did not immediately respond to a request for comment on the meeting.
